Evidence that the sigma 1 protein of reovirus serotype 3 is a multimer
J Virol.

Abstract
In this report, we study the reovirus serotype 3 (strain Dearing) sigma 1 protein obtained from various sources: from Escherichia coli expressing sigma 1 protein, from reovirus-infected mouse L cells, and from purified reovirions. We demonstrate that the sigma 1 protein is a multimer in its undisrupted form and present biochemical evidence suggesting that the multimer is made up of four sigma 1 subunits.
